I remember seeing a speed mod kit for the Legacy lower carbon cowl on the internet awhile back.  However, recent searches were unsuccessful in finding that information/advertisement again.  Has anyone seen or heard of that "kit" before or has experience with it or knows if it is still being offered?  I recall that the design purpose was to reduce drag via reducing the "wetted area" by streamlining the cowl closer to the exhaust system?  Thanks in advance for any info or insight on the product.
